Elastic element of support of a part of the body

Abstract

An elastic element of support of a part of the body is characterized by the fact that when applied singularly or in a plurality of pieces on the frame of a chair or other similar apparatus makes totally flexible in every direction the parts of the apparatus which are in contact with the body of the user.

What is claimed is:  
     
         1 . An elastic element supporting a part of the body, characterized by the fact that when it is applied singularly or in a plurality of pieces on the frame of a chair or similar apparatus, makes totally flexible in every direction the parts of said apparatus which come in contact with the body of the user.  
     
     
         2 . The elastic element according to  claim 1  characterized by the fact that it is constituted by a monoblock ( 1 ) made of plastic material which comprises a hollow sleeve ( 2 ) and a bellows ( 3 ).  
     
     
         3 . The elastic element according to  claim 2  characterized by the fact that said hollow sleeve ( 2 ) is inserted with adherence on the frame ( 8 ) of the carrying structure, said structure being a chair or other apparatus.  
     
     
         4 . The elastic element according to  claim 2  characterized by the fact that bellows ( 3 ) becomes anchored to area ( 9 ) which must be endowed of a anthropomorphic motion.  
     
     
         5 . The elastic element according to  claim 2  characterized by the fact that in the anterior part of said bellows a plurality of blocks ( 4 ) protrudes and a pair of counterposed flanges ( 6 ) and ( 7 ) is hooked on said blocks ( 4 ) with a fixed joint.  
     
     
         6 . The elastic element according to  claim 5  characterized by the fact that said pair of counterposed flanges when they are mounted on the elastic element constitute a plate ( 11 ) which supports flexible area ( 9 ).  
     
     
         7 . The elastic element according to  claim 6  characterized by the fact that said plate ( 11 ) is connected to said area ( 9 ) by means of threaded connections in which the thread for screws ( 10 ) is formed on said plate ( 11 ) or in area ( 9 ).  
     
     
         8 . A chair provided with a plurality of elastic elements according to  claim 8  characterized by the fact that the portions ( 12 ) which constitute the back, the portion ( 13 ) on which the user sits, the armrest ( 14 ) and the footrest ( 15 ) are flexible.
